Force Output Compare Action for Channel 7:0 — A write to this register with the corresponding data bit(s) set
causes the action which is programmed for output compare “x” to occur immediately. The action taken is the
same as if a successful comparison had just taken place with the TCx register except the interrupt flag does not
get set.
Note: A channel 7 event, which can be a counter overflow when TTOV[7] is set or a successful output compare
Output Compare 7 Mask — A channel 7 event, which can be a counter overflow when TTOV[7] is set or a
successful output compare on channel 7, overrides any channel 6:0 compares. For each OC7M bit that is set,
the output compare action reflects the corresponding OC7D bit.
